Abstract: A camera module (300), comprising a photosensitive assembly (10), and at least two lens parts (21, 22), which are coaxially arranged. When in an operation state, the relative positional relationship between the at least two lens parts (21, 22) is adjusted by means of a driving assembly (30), such that the effective focal length of an optical system formed by the at least two lens parts (21, 22) is within a preset range. When not in the operation state, the camera module (300) has a relatively small height; and when in the operation state, the camera module (300) has a relatively large effective focal length. In this way, the technical contradiction between the overall height and a relatively large effective focal length of a traditional non-folded camera module is solved. Moreover, the driving assembly (30) is rationally arranged, such that a driver for driving the photosensitive assembly (10) and a driver for driving the lens part (22) can share driving components, thus making full use of the internal space of the camera module (300), and reducing the height of the camera module (300).

Abstract: A system and a method for rotor speed determination. The system may includes: acquiring, based on a sensor (120), a plurality of pulses associated with movement of a rotor (110) within a plurality of time periods, the rotor (110) being operably connected with the sensor (120); determining, based on a specific pulse associated with the movement of the rotor (110) within a previous time period and an actual pulse count associated with the movement of the rotor (110) within a target time period, an ideal time period for determining a speed of the rotor (110) in the target time period, the specific pulse associated with the movement of the rotor (110) within the previous time period comprising a last pulse within the previous time period or a first pulse within the previous time period; determining, based on the ideal time period or an actual pulse count within the target time period, an ideal pulse count within the ideal time period; and determining the speed of the rotor (110) in the target time period based on the ideal time period and the ideal pulse count.
